Overview
The LMX339HASD+ is a quad general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V and functions within an automotive temperature range of -40°C to +125°C. The device features internal hysteresis of 2mV for noise immunity, open-drain outputs, and low supply current consumption. It utilizes advanced submicron CMOS technology.
Feature Summary
- Internal 2mV hysteresis provides noise immunity and prevents output oscillations with slow-moving input signals
- Single-supply operation compatible with low-voltage systems from 1.8V to 5.5V
- Open-drain output configuration allows flexible interfacing with various logic families
- Automotive-grade reliability with extended operating temperature range
Applications
- Mobile communications equipment
- Notebooks and PDAs
- Automotive applications
- Battery-powered electronics
- General-purpose portable devices
Procurement Notes
Verify the specific ordering suffix 'T' if tape-and-reel packaging is required, as the base part number may default to tube packaging. Confirm RoHS compliance status indicated by the '+' suffix. Ensure the 14-pin SO package dimensions match the target PCB land pattern requirements before finalizing procurement.
Selection Notes
Select this component when high noise immunity is critical due to its built-in hysteresis feature. It serves as a drop-in replacement for LMV339 equivalents. Consider the open-drain output requirement for pull-up resistor selection. Evaluate the 14-pin SO package constraints against available board space compared to smaller alternatives like TSSOP.
Part Context
This device belongs to the LMX331/LMX393/LMX339 family of low-voltage comparators. The 'H' designation specifically denotes the inclusion of internal hysteresis, distinguishing it from the standard LMX339 variant which lacks this feature. The 'SD+' suffix indicates the 14-pin SOIC package and lead-free/RoHS-compliant manufacturing process.
